Chariots were a high tech piece of military hardware and took time to build.
They needed perfect terrain or they were just about worthless if they didn't
have it. I'd think with the development of a better, long range bow and better
shielding, the chariot just was in the way.

I think that the defeat of the Persian Empire against Alexander proved to be the decisive blow to the effectiveness of war chariots(the Seleucid Empire later used them from time to time in the early days of the empire)
For sure the war chariot lasted long in the East, especially in China

Indians used chariots in warfare for a long time..... Gupta Empire in 5th century used them.... I think other kingdoms and the Chola Empire used them upto the 10th century....

Chariots were made obsolete by armies on horseback. The Sarmations were probably the first to field enough horse borne warriors to defeat any chariot army in existence. This process began very early on, the Sarmation tribes north of Merv were horseborne by Darius's time, and probably for long before that.

Also, in the wars with the Hittites, infantry developed longer javelins which took some of the luster out of Chariot warfare.

Edit:
I will add that the Tocharians introduced horse borne warfare technology to the Asiatic tribes north of China (Xiongnu, Hsiung-nu.) These are the same guys who China built the wall to keep out. They probably defeated China's Chariot army in some unrecorded battle.

Yes. But Indian chariots were different. They were not designed to be light and swift, but they were very heavy and huge pulled by 4-5 horse, and had 4 wheels.

Nonetheless, when the Hunas started invading the Gupta Empire with cavalry armies, the Gupta Empire too started slowly replacing chariots with cavalry.

But they were still used until 10th century for purely prestige reasons.

Temples are still used today in India as Hindu temple processions, called rath-yatra -

India was at a disadvantage when facing the Sarmations, Tocharians or Huns due to the comparative availability of horses. The northerners were from the Central Eurasian Steppe.
The Gupta Empire had no one they could steal horses from, wheras the Sarmations and later the Huns probably picked a big part of the Steppe clean of horses before heading into India.

The White Huns also forced their way into Northern India.
They were descendants of the Tocharians, who were one of the first groups to have used Chariots - then later horse born warfare.
I haven't looked deeply into the White Hun chapter of the Tocharians yet.
Is there anything from the south on that subject?
